UNITED STATES LOUIS P. BLAKEY, OF GERMANTOVVN. PENNSYLVANIA.

AUTOMOBILE WASH BRUSH.

Application filed September 8, 1923.

To all whom it own concern Be it known that I, LOUIS P. BLAKEY, a citizen of the United States, residing at Germantown, in the county of Philadelphia and State ofPennsylvania, have invented certain new and useful Improvements in an Automobile Wash Brush, of which the following is a specification.

The resent invention relates to brushes of the ountain type, and more particularly to a brush for use in cleaning automobiles.

An object of the invention is to provide a brush with a shield to prevent the dripping Water from splashing or running over the back thereof and spraying or splashing the person handling the brush, the shield being adapted to collect the dripping water and carry it to the end of the brush at a suitable point of discharge so that the stream of water, mud and the like may be directed upon the ground at a point remote from the handle of the brush.

Another object of the invention is to provide a brush of this character which is made up of a plurality of separate parts including a brush head forming a portion of a hollow body or cylinder and which is separable therefrom for ready renewal of the parts, and a shield which is spaced from the body or cylinder and mounted thereon as a part of the cylinder to condense the structure and occupy small space as well as to admit packing of the device in a relatively small space.

A further object of the invention is to provide a brush with a shield and which possesses the above outlined characteristics and at the same time is compact, simply constructed, and islight in weight and easily handled, the structure and arrangement of the parts being such that the brush may be introduced into various small spaces and beneath the parts of an automobile body and chassis.

The above and various other objects and advantages of this invention will in part be described in, and in part understood from, the following detailed description of the present preferred embodiment, the same being illustrated in the accompanying draw ings, wherein:

Serial No. 661,687.

Fig. 1 is a side elevation partly in section of a brush constructed according to the present invention.

Fig. 2 is a fragmentary enlarged section taken longitudinally through the brush head and a portion of the handle.

Fig. 3 is a .further enlarged transverse section taken through the brush head substantially on the line 3-3 of Fig. 2.

Fig. 5% is an enlarged fragmentary section through the inner end of the handle and its coupling with a source of fluid supply.

Fig. 5 is a side elevation of a slightly modified form of brush. V

Fig. 6 is an enlarged longitudinal section taken through the head of the form, and

Fig. 7 is an enlarged transverse section taken on the line 7-7 of Fig. 6 through the head of the modified form of brush.

Referring to the drawings, and first to the construction of brush shown in Figs. 1 to 4, inclusive, 10 designates a handle of suitable length which is hollow and which may comprise a pipe externally threaded at opposite ends. The inner end of the handle 10 is provided with a coupling 11 which is flanged upon a feed pipe coupling 12 which may be a hose or other flexible device which permits the handling of the brush.

The brush head comprises a shell 13 which may be curved longitudinally as shown in Figs. 1 and 2, and which is semicircular in cross section as shown in Fig. 3. This shell carries bunches of bristles 14 which are arranged in suitable rows or otherwise as may be found desirable, in the shell is provided with outlet openings 15 between and about the bunches of bristles 1 1 and which extend radially through the shell relatively to the center of transverse curvature of the shell. I

The shell 13 carries a complementary section 16 which overlaps and fits into the inner open side of the shell to complete the cylindrical formation of the body. The sections 13 and 16 are sealed together by interposed packing strips 17 of rubber or other suitable elastic material. From Fig. 2 it will be noted that the outer end of the shell 13 is closed at its inner side to form a modified cap 18, and it will also be noted that the inner section 16 of the cylindrical body, at its outer end, is closed at its outer side to torn: a cap ll) ot a size to fit snugly within the cap 18 and thus unite the outer ends of the sections.

The inner end of the inner section 16 is of tubular form to provide a coupling nipple 20 which overlaps the inner end of the shell 13 and which is internally threaded tor detachable mounting upon the outer end of the handle 10.

A shield 21 which is longitudinally curved and transvcrsel bent to conform generally to the curvature oi the cylindrical body, is tilted in spaced relation about the inner side ot the body. This shield 21 has a closed end which is extended. and rounded out to contorm to the general curvature of the cap 18 and which is provided with an aperture at its axial portion to receive an endwise projecting stud 22 carried by the cap 18. The stud 22 is shouldered as shown in Fig. 2 to space the end ot the shield away from the cap 18.

The inner end of the shield 21 is attached to the cylindri ial member by a bolt 23 which may be engaged inwardly through the shell 13, the nipple 20 and through the bottom of the shield 21, a thumb nut 2st being threaded upon the bolt 23 to bind against the exterior face of the shield 21. A spacing sleeve 25 may surround the bolt 23 to space the shield 21 from the inner section 16.

Referring now to sheet 2 wherein is illustrated in Figs. 5, (3 and 7 the modified form of the invention, the handle 10 detachably carries a nipple 26 on the inner end of an inner shell section 27 which corresponds to the member 16 of the preferred form with the exception that as shown in Fig. 6 the modified form is straight and extends at an angle substantially 30 degrees from the axis of the nipple This inner shell member 27 carries the outer shell member 28 which is also straight. and a shield 29 is mounted upon the straight cylindrical head in accordance with the description above set forth in connection with the preferred form.

The construction 01 both forms of the invention is identical, the only differences being that the brush head of the preferred term is curved throughout substantially 90 degrees for gaining access to certain parts oi the automobile body and running gear, and the modified form is straight and extends at an angle to the handle sufficient to insure insertion of the brush head into close places about and beneath the chassis, the fuel tank, and other practically inaccessible parts.

The brush heads may be interchanged upon the handle 10 and various other forms of brush head may be resorted to so that a set of the brush heads may be supplied for mounting on the single handle and for carrying out ditterent cleaning operations upon an automobile or other article or device which is to be cleaned.

ater is supplied under suitable pressure through the pipe or hose 1.2, through handle 10 and into the cylindrical head, the water being sprayed through the openings 15 to the bristles lid and. to the surfaces being cleanef. 'lhis constant supply or llow o'i'i water carries otl' mud and other accumulations which are loosened or dislodged by the bristles it and tor the most part runs oil of the outer end oi" the brush head which is inclined dmvnwardly. lhc water and dirt which run over the sides oi the head are caught in the shield 21 and kept from splashing in all directions from the brush. T he shield directs the water and accumulations along the inner side of the cylindrical head and directs the flow in a single stream from the end of the head so that the stream is projected away from the handle and the operator therefore protected.

By removing the nut'2i rthe shield 21 may be quickly removed as this single bolt provides the means for coupling together the two shell sections and also the shield 21. The stud 22 on the outer end of the shell forms the means of support for the outer end of the shield and also forms the spacing member for holding the shield away from the shell to provide the trough or water receiving compartment. i i hen the bolt 23 is removed all of the parts may be separated from one another. As the nipples 20 and 26 are of the same construction they may be interchanged, as shown in Figs. 1 and 5, upon the handle 10.

It is of course understood that various changes and modifications may be made in the details o'l' construction and design of the abore specifically described embodiment of this invention without departing from the spirit thereof, all changes and modifications being restricted only by the scope of the following claims.

ll hat is claimed is:
